ADJUSTABLE LIG'I-IT SHADE AND REFLECTOR.

Specification of Letters Patent.

Patented Mar. '7, 1911.

Application filed June 6, 1910. Serial No. 565,316.

To all whom it may concern:

Be it known that I, LILLIAN HALE Srivnr, a citizen of the United States,residing at Arnim, in the county of -Wharton and State of Texas, haveinvented certain new and useful Improvements in Adjustable Light Shadesand Reflectors, of which the following is a specification.

My invention relates to new and useful improvements in adjustable lightshade and reflector.

The object of the invention resides in the provision of a shade and asupport therefor so provided with joints that the shade may be given anydesired angle of refiec tion, relative to the light, and its relativedistance from the light may be regulated.

Another object resides in the provision of a clamp member where by theshade may be securely attached to and readily removed from its support.

With the above and other objects in view tain novel features ofconstruction and operation an example of which is given in thisspecification and illustrated in the accompanying drawings, whereinFigure 1, is a side elevation of the complete device. Fig. 2, is a sideelevation of the clamp member and the universal joint carried thereby.Fig. 3, is a plan view of the socket member of the joint and the clampmember carrying the same. Fig. 1, is a plan view of the washer designedto line the joint socket. Fig. 5, represents the ball member of thejoint.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1, refers to a light shade which is supported by rods 2, and 3, hingedlysecured together by an elbow joint 4. The supporting rod 3, is securedto its support in the manner presently to be described. This rod isdesigned to extend through the opening 5, in the ball 6, as shown inFig. 1. This ball is provided with a projecting rod 7, which extendsthrough an elongated slot 8, in the socket member 9, and is outwardlythreaded to receive the thumb screw 10, by means of which the ball issecured in its socket.

The numeral 11, refers to a washer concaved so as to conform to thesocket 9, and designed to be interposed between said socket and ball 6.This washer is provided with an elongated slot 12, designed to registerwith slot 8, and receive the rod 7, and its rim projects beyond thesocket member 9, as shown in Fig. 2, and rests against the rod 3, andholds said socket member from contact with said rod.

The numeral 13, designates a laterally extending arcuate clamp memberwhich is integral with the socket member 9. and to .whieh the member1411, similarly shaped is hingedly secured as shown in Fig. 2. The freeend of member 14, carries a rod 15, hingedly secured thereto, which isdesigned to extend between the bifurcated extensions 16, of member 13,and is outwardly threaded to receive a thumb screw 17, which may bescrewed down against the extensions 16, and the members 13, and 1 1,thus secured around the supporting arm of the support. The concavedsides of these members are lined with a suitable packing material 18,which insures a firm grip of the clamp members around their supportingarm and prevents the wear of said arm. hen it is desired to elevate orlower the shade on the supporting arm the thumb screw 17, may beloosened and the desired movement effected and when it is desired toentirely remove the shade the screw 17, may be loosened sufficiently topermit rod 17, to pass entirely from between the extensions 16, and theat tachment be removed.

It is obvious that the peculiar construct-ion of the universal jointformed by the union of a ball 6, and socket 9, will provide a jointfreely movable, as the socket is held from contact and friction with red3, by reason of washer 11 and as the ball is allowed a limited rockingmovement in its socket by reason of the elongated slots 8, and 12, inwhich the rod 7, is permitted to move.

A shade and reflector constructed in accordance with the foregoingspecification and the drawings accompanying the same will be found to becapable of a ready adjustment, and will be easily attached to or removedfrom the support on which it is to be secured.

l/Vhat I claim is 1. A device of the character described including ashade support and a device for securing the same to a stationary body,said securing means being composed of a socket member and a laterallyextending clamp member carried thereb a spherical body slidingly securedon the shade support and also secured in said socket member, and a meansfor securing said clamp member to the body to which the same is designedto be attached.

2. In a device of the character described a shade and a means forsecuring the same to a stationary body, said means including a clampingdevice; a socket member carried thereby; a ball, to which said shade issecured, seated in the socket member; a means interposed between saidball and socket member for permitting the free movement of one relativeto the other and a means for regulating the freedom of movement of saidelements relative to each other.

3. In a device of the character described a universal joint, said jointcomprising a socket member and a removable lining therefor, said memberand lining each being provided with an elongated slot, said slotsregistering with each other, a ball, the said ball being provided with aprojection which extends, normally through said slots, a clamp membercarried by the said socket members, an adjustable rod passing throughthe said ball, a shade carried by said rod, and means for securing thesaid shade on the said rod.

4:. A device of the character described composed of the followingelements :-a

shade and a support therefor; a ball to which said support is secured;asocket member within which said ball seats; a means for securing saidball in its seat; a removable socket lining interposed between the balland seat; a clamp member for securing said socket member to a support; ahinge member, attached to the clamp member and designed to engage aroundsaid support and a means for securing the free ends of the clamp membersand hinge member together.

5. A device of the character described including a shade support and adevice for securing the same to a stationary body said securing meansbeing composed of a socket member and a laterally extending clamp membercarried thereby, a spherical body slidingly secured on the shade supportand also secured in said socket member, a means interposed between saidspherical body and said socket member for permitting the free movementof one relative to the other, and a means for securing said clamp memberto the body to which the same is to be secured.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
